Figure 1. Initial viscosity of allograft/polymer composites.

Non-reactive formulations were poured between 40-mm cross-hatched parallel plates, compressed to a gap of 1.5 mm, and subjected to a dynamic frequency sweep (0.1 to 100 rad sec⁻¹) at 25°C with controlled strain amplitude of 0.02% (n=3). Dynamic data was transformed steady state viscosity (η, Pa*s) as a function of shear rate (γ, s⁻¹) using a Cox-Merz transformation (geometric figures). Data were fit to the Herschel-Bulkley model (lines) to determine yield stress in the case of the LV-LD, HV-S, and HV-L formulations.
